One other thing for you. This is probably not DB technique, but I got frustrated once and frankly didn't care about any technique.
I had asked my wife to do a couple of things back when we first separated. She said no. I said right then something like "it's obvious you are not interested in talking with me about this, so since I can't read your mind, I will leave you alone". And I did, I left her alone. I was not a happy camper. I guess I basically confronted her on the fact that I could not read her mind.
Several days later, she called me and said we could talk over dinner, which we did. She told me she had to get past her anger toward me before she was willing to even see me.
I don't know as though I recommend anyone do what I did, but I just thought to myself "you know, I'm not a mind reader".
